Have you seen the youtube pre-roll ad that can be skipped after 5 seconds? The woman covers a feature of the car, and then assuming the viewer has clicked 'skip', she lingers as if she's not being watched anymore. Once she "realizes" the viewer is still there, the situation becomes humorously awkward. I think it's a very clever way for advertisers to deal with a 5 second opportunity to connect with the audience.

A classic! The expression on the guy's face as he recalls that he has AFLAC is priceless. The problem for the actor is that he could never be taken seriously in any straight roll again. The sparking ends of the broken cable are a nice touch.
